Letters .Patent No. 93,608, dated August 10, 1869.

IMPRQVEMENT IN SHUTTLE 'ron Loom Theehedule referred to in these Letters Patent and making part of the name.

To all whom it may concern -Be it known that I, CHARLES H. Flsun, of Lowell,

in the county of Middlesex, and State of Massachusetts, have invented new and useful Improvements in Shuttles; and I do hereby declare that the following is a full and exact description, thereof, reference being had to the accompanying drawings, and to the letters'of reference marked thereon.

'lhe nature of my l'lvent-ion consists in providing for shuttles a suitable device, which consists of a movable and stationary jaw or clamp, with lateral latch and spring, whereby the bobbin may be retained in the same, by it being secured by its head` 'lo enable others skilled in the art to .make and use my invention, I. will proceed to describe its construction and operation.' v

Figure l represents'a plan of one end of a shuttle, with'a bobbiu in position, held by my improved device.

Figure 2 represents a similar plan, without the bob-v bin, and parts removed to show the operation of my device.

Figure 3 represents a longitudinal section of Iig. 1.

Figure 4 represents a vertical section of fig. 2.

Similar letters in the different figures indicate corresponding parts.

The shuttle a is constructed in the usual manner, of the required size, form, and shape, its ends being provided with steel tips.

To the shuttle (t is secured my improved device, at the opposite end from the thread-delivery.

The under side of the shnttlea, is provided with a stationary jaw or clamp, b, which is firmly secured to the same, in a mortise previously prepared, which brings the same about flush with the bottom face of the shuttle a..

The top of this clamp b is furnished with a semicircular projection, c, which7 when the bobbin d is placed in position, its head resting on or against the shuttle a, tits into the groove made in the same.

0n the opposite side of the shuttle a., is a movable clam'p or, jaw, e, which is pivoted to the same, its top being furnished with a semicircular projection, j, to correspond with the projection c on the stationary clamp b, the other end of this movable clamp e being provided with a stem, y.

Located between the movable clarnpe and end of the shuttle a, is the bed-piece h, with guide i, which is secured iirmly in a niortisc previously made in the shuttle a to receive it.

with a lip, lr, which passes through an opening in thev bed-piece h, and operates against the spring I, located underneath the bedepiece It.

lhe operation is as follows:

.The latch'j is pressed laterally from behind the stem' g, which allows the movable jaw to be thrown forward, for the introduction of the bobbin. Then so introduced, and thejaw returned to its position, the pressnre is removed from the latch, and it, through the operation of the spring l against the lip Z, is again brought iu contact with the stem g, locking the jaw firmly on the bobbin.

I disclaim a clamp holding a bobbin by direct springaction; but What I claim as myinvent-ion, and desire to secure by Letters Patent, isfv 1. The combination of the stationary clamp b and movable clamp e, when held iu position by a positive locking-device, substantially as and for the purposes herein speciiied.

2. The locking-device, as described, consisting oi" the lateral latch j, lip lf, bed-piece h, and spring I, in combination with the movable clamp e, as specitied.

CHARLES H. FISKE.
